/AFTER (D)
       /AFTER[=directory-spec]

    Specifies that LSE should insert the directory or directories
    indicated into the list of source directories in back of the
    directory you specify as the value on the qualifier. If you do
    not specify a directory-spec value, LSE adds the directory or
    directories to the end of the list.

    If you do not specify either the /AFTER qualifier or the /BEFORE
    qualifier, LSE replaces the entire directory list.
